Chopper-Stabilized Hall Effect Bipolar Switch
A3230
exhibiting negative switch behavior operate in a similar but
opposite manner. A north polarity
fi
eld of suf
fi
cient strength,
> B
RP
, (more north than B
RP
) is required for operation, although
the result is that V
OUT
switches high, as shown in panel C. When
the
fi
eld is reduced beyond the B
OP
level, the device switches
back to the low state.
The A3230 is designed to attain a small hysteresis, and thereby
provide more sensitive switching. Although this means that
true latching behavior cannot be guaranteed in all cases, proper
switching can be ensured by use of both south and north mag-
netic
fi
elds, as in a ring magnet.
Bipolar devices adopt an indeterminate output state when
powered-on in the absence of a magnetic
fi
eld or in a
fi
eld that
lies within the hysteresis band of the device. The correct state is
attained after the
fi
rst excursion beyond B
OP
or B
RP
.

Applications
It is strongly recommended that an external bypass capacitor be
connected (in close proximity to the Hall sensor) between the
supply and ground of the device to reduce both external noise
and noise generated by the chopper stabilization technique. As is
shown in Panel B of
fi
gure 1, a 0.1μF capacitor is typical.
